T0 ILZZ whom it 772/601] concern:

Be it known that I, MERVIN M. RUB IGHT, a citizen of the United States,residing at Hartville, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Cornet-Mouthpieces; andI do hereby declare that the following is a full, clear, and exactdescription of the same, reference being hadto the annexed drawings,making a part of this specification, and to the figures of referencemarked thereon, in which Figure 1 is a perspective view of themouthpiece complete. Fig. 2 is a view showing the mouthpiece before thesame has been plated or covered. Fig. 3 is a longitudinal section.

The present invention consists in providing a mouthpiece or embouchurefor wind instruments wherein the metal portion of the mouthpiece isprovided. with what might be termed an integral shell of vulcanizedrubber or other'suitable material and especially protecting the portionof the mouthpiece which comes in contact with the lips, therebypreventing any contamination or injury to the lips and enabling theperformer to play with much greater ease and certainty than is possiblewith the metal mouthpiece or the so-called elasticcovered mouthpiece.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 represents the mouthpiece, which isoriginally formed of the usual shape and size, and 2 the stem, saidparts being formed integral with each other. The inner periphery of themouthpiece 1 is provided with the shoulder 3, which shoulder is locatedadjacent the passage 6 formed in the stem 2, said shoulder being for thepurpose hereinafter described. Upon the outer and inner surfaces of themouthpiece 1 is located a layer of vulcanite rubber which is broughtinto position while in a plastic state and afterward hardened, whichprocess causes the rubber to closely adhere to the metal of themouthpiece 1. The rubber coating is formed of such a thickness that itwill entirely cover the metal portion of the mouthpiece, thereby leavingno metal exposed to contact with the lips of the player. The rubbercoating 5 is extended beyond the outer edge of the mouthpiece and itsextreme end formed flat or of any other shape suitable for theparticular case or kind of instrument designed to have the mouthpieceattached.

It will of course be understood that the outer form of. the rubber maybe varied without departing from the nature of my invention, as the onlyobject to be accomplished is to provide such a form that will be easyupon the player and at the same time enable the player to fully closethe mouthpiece during the time it is in use. By using the rubber or likematerial and applying it as above clescribed a material is betteradapted for con tact with the lips of the player,first, in a sanitarysense; second, not being subject to thermal change, and, third,providing a better contact as between the lips and the mouthpieceitself.

It is well understood that in order to cause the rubber or like materialto properly adhere to the metal the surface of the metal upon which therubber or like material comes in contact should be roughened to acertain extent or non-polished, so that there is no danger of the rubberor other member becoming detached fiom its matrix constituting themouthpiece. This feature of roughness is illustrated in Fig. 2.

For the purpose of providing a continuous surface between the open endof the mouthpiece and the air-passage 6 through the stem 2 the shoulder3 is provided, which shoulder constitutes an abutting edge or flange forthe rubber or other material, and after the rubber or other material hasbeen properly connected and attached a continuous or smooth surface isprovided at the junction of the rubber or like material and metalportion, so that there can be no interference or any obstruction to thepassage of air during the time an'instrument is being played. Byproviding the coating upon the inner surface of the mouthpiece andforming the same of various thicknesses I am enabled to change thecontour of the embouchure, thereby making the mouthpiece suitable forhigh or low tone or any other abnormalities or peculiar conditionrequired by the individual.

It is a well-known fact that by continued use of metal mouthpieces theplayers are subject to cancerous sores in the mouth due to verdigrispoisoning; but by my peculiar arrangement this di'liiculty is avoided.

I Having fully described my invention, what l I claim as new, and desireto secure by Letters Patent, is

1. A mouthpiece for wind instruments, the inner periphery of saidmouthpiece provided with a shoulder located near the junction of the cupand the passage of the stem, and a vulcanized coating fixedly attachedto the cup upon the inner and outer surfaces thereof, and constitutingan integral portion thereof, and adapted for lip contact, substantiallyas and for the purpose specified.

2. A mouthpiece consisting of a metal base, said base having a roughenedsurface, a coating of vulcanized rubber secured to the inner and outersurfaces of said mouthpiece and embedded in said'roughened surface andthe vulcanized rubber adapted for lip con tact, substantially as and forthe purpose specified.

3. A mouthpiece for wind instruments provided with an integralvulcanized rubber coating upon its inner and outer surfaces and ashoulder located at the junction ol the mouthpiece and air-passage,substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
